SKIPIPING DEVICE.

Application filed August 7, 1924. Serial No. 730,559.

This invention relates to a skipping device or jumping rope such as commonly used by athletes and other persons for training or physical exercise, and such as commonly used by children in sport. It is convenient to have handles at the ends of the rope. In the structures of the prior art, as the rope swings about the handles, the same has been caused to twist and chafe so that the rope or flexible member soon became worn.

It is an object of this invention, therefore, to provide such a shipping device comprising a flexible member and handles secured thereto in such a manner that the ends of the rope revolve around a longitudinal axis of said handles without any twisting or torsion thereon.

It is another object of the invention to provide such a device comprising a flexible member preferably of leather, the ends of which are formed with loops and rotatably mounted on a member extending longitudinally from a handle.

It is still another object of the invention to provide such a device comprising a flexible member and handles at each end thereof, each handle having a journal member extending axially therefrom on which the end of the flexible member is journaled, together with means for holding the end of the flexible member thereon.

These and other objects and advantages of the invention will be fully set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to the same parts throughout the diflerent views, and in which,

Fig. 1 is a view in front elevation of the device showing the handles in operative position;

Fig. 2 is a partial view in front elevation of one end of the device, a small portion thereof being shown in vertical section; and

Fig. 3 is a vertical section taken on the line 33 of Fig. 2, as indicated by the arrows, Figs. 2 and 3 being shown on an enlarged scale.

Referring to the drawings, the device is seen to comprise a flexible member 1. While this member may be of any suitable flexible material, it has been found, in practice, that leather is a very desirable material for the structure used and such leather is preferably made of flattened or oblong shape in cross section. Each end of the flexible member is formed into a. loop 1 by having the end bent reversely alongside of the member and secured by wire loops 2 or in any other suitable manner. A handle 3 is provided for each end of the device of convenient shape to be grasped in the hand, and said handle has projecting from one end-thereof and forming a part thereof and axially alined therewith, a journal member 4. While this journal member may be of various shapes, in the embodiment of the invention illustrated, the same is shown as a simple headed screw threaded into the end of the handle 3, the usual ferrule 5 being provided at said end. of the handle. The member 4 is encircled by the loop 1* and Washers or disks 6 of slightly larger diameter than the loop are disposed at each side thereof and also journaled on the member 4. The head 4* of member 4 forms a holding means for holding the washers 6 and loop l thereon.

In operation, the person using the device Will grasp the handles 3 having one in each hand and the handles will be held substantially in the position shown in Fig. 1 and the flexible member 1 swung about the axis of said handles in close proximity to the ground or floor 7. It will be seen that the ends of the member 1 are always disposed substantially at right angles to the axis of the handle 3 and as the member revolves, these ends and loops 1 will merely revolve about the member 4: and in a plane at right angles to the axis thereof. There will therefore be absolutely no twisting or torsional stress placed on the ends of the flexible member 1 and there will practically be no wear or abrasion thereof adjacent the handle. The loop 1 and washer 6 are loosely mounted on the member 4:.so that there is practically no friction or resistance to the revolution of the flexible member. As stated, the member 1, preferably, is made of leather, which material is stiffer than the ordinary fabric rope and retains its position at the portion adjacent the handles in a better manner. The flattened structure of the leather also offers less resistance in movement through the air. The structure of the flexible member adj..- cent the handle, however, is entirely applicable to the ordinary rope.

From the above description it is seen that applicant has provided a very simple and efficient skipping device. The same can be easily and inexpensivelymade and is very strong and durable. The device has been amply demonstrated in actual practice and found to be very successful and eificient and the same is being commercially*ma'de.

It will, of course, be understood, that .various changes may be made in the'form, details, arrangement and proportions ofthe parts without departing from the scope of applicants invention, which, generally stated, consists in such a device as shown and described and defined in the appended claims.

lVhat is claimed is:

1. A jumping rope comprising a flexible member having a handle at each end, a -journal member extending axially .l'rom said handle and rigid therewith, .a single loop formed by one end of said flexible member surrounding said journal member, and disks for holding said loop in position-on said journal member.

2. A skipping device comprising a flexible member, a handle at the--endthereofla journalmember extendingiaxially from said handle, said flexible member having a loop formed in its end. embracing said journal -member, a-disk journaled on said journal .member at each side of said loop, said ournal member having means for holding said d sks andloop thereon.

3. A skipping device comprising a flexible .member rotatably mounted on a handle at -eachzen'd thereon-said flexible .member being formed of flattened leather.

side bearings on saidspindles at each side of i said. loops adapted to holdsaidloops on said :spmdlesand permit theeasy rotation-of the loops about the same.

In testimony whereoflafiix my signature.
